Forum rules
The DIY forum is for personal projects (things that are not for sale, not in production), info sharing, peer to peer assistance. No backdoor spamming (DIY posts that are actually advertisements for your business). No clones of in-production pedals. If you have concerns or questions, feel free to PM admin. Thanks so much!

Even more mods to the Blackfly/ScrapYard.Arcade button to generate sound. Toggle between a searing synth sound or a dark bass/drone. Fine tune or mangle with side knob. Add noise that follows the delay time with the last toggle.

A dude on DIYsb's made a delay that adds ring mod to the repeats, I got board from him for just general purposes but I thought of your scrap yard when I got it .. I might try to copy your delay add idea, but use the ring mod delay .. nice work man. It's inspiring.

Absolute beginner here, on the left, my very first build, a Bazz Fuzz (Fuzzdog kit), that worked right away. Then I got excited and tried to build a ColorTone Bass Fuzz next, which of course isn't working ....

Tired of trouble shooting, I decided to go back to 1-knob fuzzes and built another Bazz Fuzz, the one on the right, this time using a different diode and socketing the transistor.

Next up is a Dark Grime, then I'll try a Mojo Dust. After that I might go back to trouble shoot that damned ColorTone ...

I agree with that sentiment. i've learned more about building/how things work from busting out a multimeter than anything else. And thank you i appreciate the consideration

It probably sounds just as good or better.

Thanks. I do my best to make them sound good, looks are a secondary consideration when you're working with junk.I think all the cool builds in this thread represent what the big corps and hi-end guys are missing about the whole music scene in general. Musicians are individuals and want to reflect that individualism in their music and with their gear.

Thanks. I think that sound is due to the relatively low voltages (250V B+) the amp runs at because of the 6X5GT rectifier tube.

I'm bummed I didn't have this finished in time for BILF, but it's done now! This is the newest version of the fancy ABY I've been working on! There's still a little noise due to the output stages not being grounded when they aren't in use, and I'm still working out exactly what I want out of this thing, but I'm pretty happy with this one!

Technical bullshit: (reads like a vague sales pitch so nsfw, proceed with caution)

It uses two effects loops, A and B, and lets you run just A, just B, Y, series with A>B, and series with B>A. The mode you're in is lit up purple at the top, and red/blue leds tell you exactly where the red and blue switches (center and right most) will take you. You can switch what order the modes cycle in by double tapping the phase inverting switch on the left. A single tap on the left switch just inverts the phase on loop B just in case there's any phase issues.

It does trails when switching away from a loop if you want, and can also leave the input connected so time effects can fill up before you switch to them. There's toggle, momentary, and both together modes for the foot switches as well.

It outputs to one or two amps, and gives you two options for the series modes. In one setting, one amp is left silent and the other amp gets the signal from the two loops in series. In the other mode, after your signal goes through the first loop it splits and goes to one amp while also going through the second loop and out to the second amp. When using only one amp, both modes still work, but the second mode leaves you mixing signal from just one loop with signal from both loops at the end before leaving the pedal.

There's a light boost of about 6db, which also attenuates down to zero to help manage levels. The whole thing can run at 9v or 18v for more headroom, and I'm only building simple fuzzes from now on.

First finished pedal y'all. T-Amp PCB from Mask Audio Electronics. An easy build which I did in parallel with three other circuits (yet-to-be-boxed). Of course the enclosure was the most time-consuming. I drilled, sanded and washed it, then sprayed it with a grey base coat, then pink (sanded), then painted it with various model paints I had lying around, and finished it with like 5-6 coats of clearcoat.

The inside looks a bit rough but everything works. Had to mount the short-legged pot above the PCB with some solid copper phone wire. Fitting the LED was among the more difficult things, it's a big one and wouldn't fit under the circuit board as I had hoped (guess I could have mounted it sideways). I used one of those transparent round LEGO "lights" as a bezel (need to lacquer the top, that sunken hole is gonna collect dirt) and Sugru mouldable glue holds it in place. Floating 5.6k resistor for extra dimness.

Oh, and it sounds great! Can't wait to box up the SFD next (also from MAE).
